Abstract
The aim of this work is to study cases of ureteropelvic junction obstruction of different age groups and to evaluate the outcome of monument by different treatment modalities especially open surgical and endoscopes procedures. We are also aiming that at the end of the study we would able to define the criteria which would make the upjo more suitable for treatment by specific technique hoping to formulate some recommendations towards proper patient selection.
In conclusion ,there are many factors to consider regarding the optimal surgical procedure to perform on a given patient .anatomic considerations, past surgical procedures, patient expectations, and the surgeon s experience all contribute to the success of the procedure. we concluded that open dismembered pyelolasty is still considered the gold standard for management upon especially in pediatric age group. There was no difference in out come whatever the type of diversion used after dismembered pyeloplasty. However, there was significant difference in length of hospital stay between the use of jj stent alone and the use of Cumming or nephrostomy tube. the shortest hospital stay was found with the use of internal stent alone while the use of Cumming or nephrostomy tubes was associated with prolonged hospitalization.
We suggest that preoperative imaging for detection of crossing vessels in primary upjo can be eliminated, provided that the incision is carried out in a purely lateral position. however, it may be respected to primary cases with renal anomalies or melioration and secondary cases where scaring and adhesions carry the risk of parenhymal injury with a purely lateral incision. In this condition, preoperative imaging with ct angiographies is important because if no vessels are present, a direct posterior or post lateral incision may be more suitable to minimize the risk of parenchyma injury.
